More powerful than ever before – the new GWS 18V-15 C Professional, GWS 18V-15 SC Professional and GWX 18V-15 SC Professional Biturbo angle grinders from Bosch for professionals. All three tools are optimized for use with ProCore18V 8.0 and 12.0 Ah batteries: The specially developed, brushless high-performance motor has been perfectly coordinated with the electronics and battery, meaning that the high-power currents of the inserted ProCore18V batteries can be used to their full potential. The result: The performance of the Biturbo angle grinders is comparable to that of a 1,500 watts corded tool. The tools work up to 50 percent faster than the current most powerful cordless angle grinder from Bosch – the GWS 18V-10 SC Professional. The range of applications is therefore wider because, for the first time, especially power-intensive cutting, roughing and grinding applications are possible – lasting the full lifetime of the tools. They are exceptionally durable and robust.

High level of occupational health and safety leads to increased productivity

The Biturbo angle grinders are ten percent shorter than comparable competitor models and, with a grip circumference of just 164 millimeters, they fit comfortably in your hand. They offer tradespeople comprehensive user protection. This includes sensor-based functions such as “Drop Control” and “KickBack Control”. “Drop Control” stops the motor as soon as the tool hits the floor after it falls, while “KickBack Control” stops the motor if the angle grinder is suddenly blocked, for example if the wheel jams. Furthermore, all three tools are equipped with a braking function. This means that, for example, the GWX 18V-15 SC Professional, the new model with X-Lock for tool-free accessory change, comes to a complete stop within one second thanks to “X-Brake”.

Soft start, restart protection and an auxiliary handle with vibration damping provide the user with more control over their work. The result: Greater productivity in day-to-day work.

Added value and operating comfort thanks to connectivity functions

The new Biturbo angle grinders also offer added value and increased operating comfort thanks to the connectivity functions. Tradespeople can connect it to their smartphones, for example, to easily adjust the speed. This is where the GWS 18V-15 SC Professional and GWX 18V-15 SC Professional models offer a particular advantage: In order to adjust the speed even more precisely to suit the relevant application, three additional preset speed levels can be added to the existing three, thereby increasing the number to six. All of the speed values can be set individually here. For all three models, care and maintenance are made easier by connectivity: Tradespeople receive information about the tool status on their smartphone. Furthermore, users can send repair orders more quickly via the app. GWS 18V-15 SC Professional and GWX 18V-15 SC Professional also score points for their user interface: Professionals always have an overview of the tool status and the battery’s current charge status, and can also conveniently set the speed level via the display.

Full compatibility in the Bosch Professional 18 volt system

The ProCore18V 8.0 Ah and ProCore18V 12.0 Ah high-performance batteries, which are used to power Biturbo angle grinders in the most efficient way, are part of the Bosch Professional 18 volt system. It guarantees the compatibility with existing and new professional power tools and chargers in this voltage class for lithium-ion batteries. This results in planning and cost security for tradespeople and companies.

In total, Bosch is introducing eight Biturbo tools: Three angle grinders, three saws and two rotary hammers. They are more powerful than all previous cordless tools from Bosch and offer professionals the equivalent power of a 1,000 to 1,800 watts corded tool. For further information, see PI 10894 .

The GWS 18V-15 C Professional, GWS 18V-15 SC Professional and GWX 18V-15 SC Professional Biturbo angle grinders will be available from September 2019. All prices are recommended retail prices excluding VAT.
